To all whom 'it may concern: 4

Be it known .that I, FRANK- J. LEARMAN, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a new and useful Improvement in vBlackleadi'n -Machines, of

. which the following is a spec' cation.

forcing the liquid t ough a mova le discharge s out against -the surfaceof the matrix in t e bath to coat the same with the black lead, andthisl ump preferably takes the li uid from the ath so as to keep thesame 1 uid in circulation.

The o ject ofthis invention is to provide an actuating mechanism for themovable discharging spout which will be simple in construction andpositive 1n o eration and which will automatically move t e dischargespout back and forth in different directions, or universally over thematrix so that the entire surface of the same 'Will be completely andevenly coated with the black lea In the accompanying drawings: Figure 1is a perspective view of a matrix coating machine provided with a spoutactuating mechanism embodying the invention. Fig. 2 is a plan viewthereof, partly in-section, showing various different positions of thedischarge s out in dotted lmes. Fig. 3 is a sectional e evation thereofin line 3-3, Fig. 2.

Like letters of reference refer to like in the several figures.

A represents the tank for containingl. the black lead bath in a matrixcoating mac ine, B a pump connected therewith by an intake pipe b andprovided with a discharge pipe b', a portion at least of which isflexible and terminates in a suitable nozzle b2. C re resents a Wax-matrix which rests in the tank eneath the nozzle b2 upon a support orframe D. All of these parts may be of any suitable or usualconstruction. v

v E and F represent vertical shafts jourparts driving the verticalshafts E and naled in suitable bearings e f on two sides ofv the tank Aand provided at their upper ends with cranks e and f which are connectedby pitmen or links e2 and f 2 to the free end of the discharge spout.The tpitmen are preferably connected by ball an socket joints e3 and f3to a clamp g embracing the spout to allow a free movement of the spoutin different directions.

Any suitable means may be em loyed for In the construction shown, driveshafts H and I are journaled in suitable bearings on the sides of thetank A at which the crank shafts E and F are located, and are connectedby intermeshing bevel gears h and 'i which cause them to turn inopposite directions. One of the shafts, for instance the shaft H, isprovided with tight and loose Tpulleys K for a belt for drivingthisshaft. he drive shafts H and I are connected to the crank shafts E and Fby intermeshing bevel gear wheels Z and Z', respectively. Thisarrangement of the shafts and connecting gears causes the vertical cranklshafts to revolve in opposite directions, and the gears are soproportioned that the crank shafts are driven at different speeds. Thecranks e andf are also preferably of different lengths. By reason ofthis arrangement of the shafts and gearing, the cranks continuallychange their relation to each other and shift the discharge spout towhich they are connectedv in different directions, and to differentpositions. As the cranks travel at vdifferent speeds, they can onlyoccupy the 'same relation to each other after a number of revolutions oftheir cranks, depending upon the relative speed of the same. The spoutis therefore moved back and forth over the matrix in different paths andeventually repeatedly covers'all parts of the matrix. A feW of the manydierent positions of the cranks and discharge spout are shown by fulland broken lines in Fig. 2. The same results can be secured by anysuitable drive mechanisms for rotating the cranks in opposite directionsat different speeds. The parts of the actuating mechan ism should beproportioned and arranged to give the most effectual movement of thespout and prevent the same from assuming a dead center position orcoming into contact with the Walls of the tank.

I claim asmy invention: 1. In a black-leading machine the c ombichargingliquid against the su ace of a ma-.

trix in said tank, cranks located on different sides of the tank andconnected to said s out, and means for revolving said cranks at dier entspeeds, whereby the spout is shifted to various different positions inthe tank, substantially asset forth.

3. In a black-leading machine the combination of a tank, a movable s outfor discharging liquid against the su ace of a matriX in said tank,cranks located on different sides of the tank and connected to saidspout7 and means for revolving said cranks in opposite directions at`different speeds whereby the spout is shifted to various different.posis tions in the tank, substantially as set forth.

4. In a black-leading machine the combination of a tank,.a movable s outfor discharging liquid against the s trix in said tank, cranks locatedon different sides ofthe tank, links connected to the cranks, universaljoints connecting the links ace of a ma-` to the spout, and meansforrevolving said cranks `1n o` posits directions at different` s eedsWhere y the spout is shifted" to various rfferent positions in the tank,substantially as set forth. l

5. In a black-leading machine the combination of a tank, a movable s outfor discharging liquid against the su ace of a matrix 1n said tank, twoactuatin devices con-` nected to said spout for'control ing the movementthereof, and mechanism for producing a relatively different motion ofsaid actuating devices whereby they cause an irregular movement of saidspout, substantially as set forth.

6. In a black-leading machine thecombi-` nation with a tank, a movable,discharge spout emptying into said tank, actuating arms connected withsaidspout and arranged at an angle to each other, and means for movingsaid arms at diHerent speeds whereby said spout is shifted to variousdifferent ositions in the tank, substantially as set orth.

Witness my hand, this 7th day of May,

A FRANK J. LEARMAN.
